Patent EP-0007827-A1 (EP)
Title: Gyromètre à laser
Inventor: PIRCHER GEORGES
IPC: G01C19/72
Filed: 1979-06-29
Abstract: L'invention se rapporte aux gyromètres à laser grâce auxquels on détermine une vitesse angulaire par la mesure de la différence de phase entre deux faisceaux lumineux cohérents guidés dans une fibre optique enroulée, respectivement dans le sens de la rotation dont on mesure la vitesse et en sens inverse. Dans le gyromètre selon l'invention, les deux faisceaux lumineux (1) et (2) guidés dans la fibre sont issus d'un faisceau unique (10) séparé spatialement en deux parties par un élément optique à deux faces réfléchissantes (4). A leur sortie de la fibre, ils sont dirigés par le même élément optique en sens inverse et forment deux parties adjacentes (21 et 22) d'un faisceau. La mesure du déphasage entre les deux parties est basée sur le déplacement du maximum de la tache de diffraction obtenue dans le plan focal d'une lentille placée sur le trajet de ce faisceau. L'invention s'applique à la mesure de vitesses angulaires avec un bon rapport signal sur bruit.

Abstract: The filter (1) comprises a rotor or impeller (15) carrying a blade element (21) contained into a space (22) enclosed by a foil grate (23,23'). The oil pressure generated by the oil pump causes the rotation by reaction of the rotor or impeller and of related blade element so that the latter, by centrifugal effect, separates from the oil all the impurities which are retained by the grate. The oil is supplied to the rotor or impeller through passages (5,17,18) upstream of the grate and is exhausted at cleaned condition through passages (11,12,13,4) located downstream of the grate (Fig. 2).

Abstract: N-sulfinyl carbamates having the general formula
     are novel compounds. They are useful as pesticides, particularly insecticides, and are applied to crops and other loci where pests are to be killed. Pesticidal compositions contain such compounds. The compounds are produced by reacting a carbamate of the formula
     with an equimolar amount or molar excess of thionyl chloride to produce a compound of formula R 2 -O-CO-NR 3 -SOCl, which constitutes another embodiment of the present invention, and reacting the latter with a suitable nucleophilic reactant. In the formula R is one of certain hydrocarbon and substituted hydrocarbon and imino groups, R' is C 1-4  alkyl, phenyl or one of certain substituted phenyl groups, and R' is the residue of certain nucleophilic reactants. 
     The pesticidal compounds of the present invention retain the insecticidal activity of the carbamates from which they are derived but are lower in mammalian toxicity.

Abstract: A process for the extrusion of melt-processable liquid crystal polymer comprising the steps of subjecting the liquid crystal polymer to an elevated temperature between the DSC transition temperature and the degradation temperature of the polymer, cooling the liquid crystal polymer to a processing temperature which is between the DSC transition temperature and the elevated temperature and at which the liquid crystal polymer is less subject to degradation than at the elevated temperature, and extruding the liquid crystal polymer into the form of a shaped article having mechanical properties. The liquid crystal polymer exhibits at the elevated temperature a reduction, in the melt viscosity which reduction is substantially retained by the liquid crystal polymer at the processing temperature. The liquid crystal polymer is extruded into the form of a shaped article while the reduction in melt viscosity is thus retained. (By employing the present process, melt processable liquid crystal polymers can be conveniently processed at temperatures near the DSC transition temperature rather than at the higher temperatures commonly encountered in the prior art at which degradation is more likely to occur).
